Ⅲ Note on consumable parts
The following parts are consumable and should be replaced
after a certain number of hours or a count of operations.
The service lives given below are only typical values. They
may vary depending on the operating environment and con-
ditions.
Note that the replacement of consumable parts is charge-
able even when they are replaced before the termination
of the warranty period.
• Zoom lens assembly
Zooming operation : 2 million times
Focusing operation : 4 million times
• Slip rings : 5 million operations
• Cooling fan : Approx. 30,000 hours
• Alarm output 1 relay : 200,000 times of operation
Ⅲ Note on auto focusing
Although this unit incorporates a one-push auto-focusing
system and EASY AF functions, auto-focusing may some-
times be impossible depending on the object and camera
setup. In this case, adjust the focusing manually.
Objects and images with which auto focusing may be
difficult:
• When the image brightness is extremely high.
• When the image brightness is extremely low.
• When the image brightness varies continuously (for ex-
ample when the object is a flashing light).
• When the image contrast (difference between bright and
dark) is very poor.
•When the image does not contain a vertical contour com-
ponent.
• When vertical stripe patterns recur on the screen.
Camera setups with which auto focusing may be diffi-
cult:
• When the AGC is activated and the image is coarse.
• When SENSE UP is activated and the image contains
only little motion.
• When electronic zooming is activated and the image does
not contain a large enough contour component. (In the
case of TK-C676 only)
Ⅲ Zooming
When zooming is stopped near the TELE end during manual
operation or by selecting a preset position, focusing may
deviate slightly. In addition, the manual zooming operation
may not always be smooth.
These phenomena are due to the characteristics of the built-
in lens and are not malfunctions.
Ⅲ Preset positions
• The zooming position of the camera can be set to a total
of 100 preset positions, including the home position.
• The electronic zoom can be preset up to x2.
However, if the electronic zoom menu on the screen is
set to OFF even presetting the electronic zooming to x2 ,
the camera itself moves to the preset position without the
electronic zooming being activated. (TK-C676 only)
• It is not permitted to preset the electronic zoom to a larger
ratio than x2. The message "INVALID POSITION
(D.ZOOM)" will appear on the screen if a larger ratio than
x2 is set. (TK-C676 only)
• The TILT position can be set and operated only between
0° to 90° even when the item “FLIP” is set to DIGITAL.
(A TILT position between 91° and 180° cannot be set or
operated. The message "INVALID POSITION (TILT) will
appear on the screen if a larger TILT position than 90° is
set. )
